JS answer: function meeting(s) { let string = s.toUpperCase().split(';').map(x => x.split(':').reverse().join(', ')).sort().join(')(') return '(' + string + ')' } const meeting = (s) => s.toUpperCase().split(';').map(name => name.split(':').reverse()).sort().map(name => (${name.join(', ')})).join('') and more...

John has invited some friends. His list is: s = "Fred:Corwill;Wilfred:Corwill;Barney:Tornbull;Betty:Tornbull;Bjon:Tornbull;Raphael:Corwill;Alfred:Corwill"; Could you make a program that makes this string uppercase gives it sorted in alphabetical order by last name. When the last names are the same, sort them by first name. Last name and first name of a guest come in the result between parentheses separated by a comma. So the result of function meeting(s) will be: "(CORWILL, ALFRED)(CORWILL, FRED)(CORWILL, RAPHAEL)(CORWILL, WILFRED)(TORNBULL, BARNEY)(TORNBULL, BETTY)(TORNBULL, BJON)" It can happen that in two distinct families with the same family name two people have the same first name too.

given a string, replace every letter with its position in the alphabet. If anything in the text isn't a letter, ignore it and don't return it. "a" = 1, "b" = 2, etc. Example alphabetPosition("The sunset sets at twelve o' clock.") Should return "20 8 5 19 21 14 19 5 20 19 5 20 19 1 20 20 23 5 12 22 5 15 3 12 15 3 11" (as a string) The sunset sets at twelve o' clock. = 20 8 5 19 21 14 19 5 20 19 5 20 19 1 20 20 23 5 12 22 5 15 3 12 15 3 11 another example: "The narwhal bacons at midnight." = "20 8 5 14 1 18 23 8 1 12 2 1 3 15 14 19 1 20 13 9 4 14 9 7 8 20"

You have an array of numbers. Your task is to sort ascending odd numbers but even numbers must be on their places. Zero isn't an odd number and you don't need to move it. If you have an empty array, you need to return it. Example 5, 3, 2, 8, 1, 4 will be 1, 3, 2, 8, 5, 4 5, 3, 1, 8, 0 will be 1, 3, 5, 8, 0 gdluck...

Given an array try to find and return all odd numbers let's say you have 20,1,-1,2,-2,3,3,5,5,1,2,4,20,4,-1,-2,5 The Answer would be: 1, 3, 3, 5, 5
